Reinforcing the subject, this is using Linux - to be specific, FPC
2.4.2-0 under 64 bit Mint 9.
I'm trying to convert a large number of MP3 files to Ogg Vorbis.
This is a two step process, first I run mpg321 to switch them to a
.wav file, then oggenc to convert to a .ogg
What's driving me crazy is that running the two commands via
ExecuteProcess does the first step OK, but oggenc fails with an exit
code of 1, operation not permitted.
If I replace the ExecuteProcess with a call to fpSystem, concatenating
the CommandString and ParamString with a space as separator and
passing that as the command, both steps work just fine.
I've tried putting a Delay(5000) between the two commands using
ExecuteProcess, just in case there was some type of problem with data
still being written from a cache. No difference whatever.
This is reproducible on a whole batch of files, and yes, I've checked
all the file permissions.
It's got to be something obvious, or some quirk of Linux programming
that I haven't met up with yet (I'm still a novice with FreePascal and
Linux, though I've many years experience with Delphi and Windows).
What am I missing?
Thanks,
Brian.
